POWER INPUT Voltage: 100-264 V ac 1 phase. Frequency 50-60 Hz nominal
OUTPUT Voltage: 82 V d. C. @ 200 V a. C. Current continuous 4A(De-rate by 12% if mounted in 'portrait' orientation) . Transient 7.5A for 10 secs. Resistance 15 ohms min (10 ohms min when input volts is less than 175 ac)
REGULATION: +/- 1.0%(With 4% engine governing)
THERMAL DRIFT: 0.03% per deg. C change in AVR ambient(After 2 minutes）
TYPICAL SYSTEM RESPONSE AVR response: 20 ms Filed current to 90%: 80 ms Machine Volts to 97%: 300 ms
EXTERNAL VOLTAGE ADJUSTMENT: +/-10% with 1 k ohm 1 watt trimmer (Generator de-rate may apply), Increasing resistance lowers voltage.
UNDER FREQUENCY PROTECTION: Set point: 94 -98% Hz(Factory set, semi-sealed, jumper selectable).
UNIT POWER DISSIPATION: 12 watts maximum
BUILD UP VOLTAGE: 4 Volts @ AVR terminals
ANALOGUE INPUT Maximum input: +/- 5 Vdc,Any device connected to the analogue input must be fully
floating (galvanically isolated from ground), with an
insulation strength of 500V ac. Sensitivity: 1V for 5% Generator Volts (adjustable) Input resistance 1k ohm
QUADRATURE DROOP INPUT: 10 ohms burden Max. Sensitivity: 0.07 A for 5% droop 0PF Max. Input: 0.33 A
OVER EXCITATION PROTECTION: Set point 75 V dc Time delay 10-15 seconds (fixed)
ENVIRONMENTAL Vibration: 20-100 Hz 50mm/sec 100Hz -2kHz 3.3g
Operating temperature: -40 to +70℃ (De-rate output current by 5% per degree C above 60C)
Relative Humidity: 0-70℃ 95%(Non condensing).
Storage temperature: -55 to +80℃

Product Function Description:

This product has undergone rigorous quality testing
Durable and easy to install and replace
The most cost-effective and best after-sales service
Quality assurance that gives you peace of mind

Features:

The AVR is linked with the main stator windings and the exciter field windings to provide closed loop control of the output voltage with load regulation of +/- 1.0%.
Over excitation conditions are limited to a safe period by a protection circuit within the AVR.
Provision is made for the connection of a remote voltage trimmer, allowing the user fine control of the generator's output.
An analogue input is provided allowing connection to a Newage Power Factor controller or other external devices with compatible output.

Package Includes:

1 × Automatic Voltage Regulator
